I recently had two print failures on my Ender 3 Neo. In both, it looked like the part came free from the heated build plate after about an hour or so of printing. Both had good starts in the first 15 minutes or so. I had a successful print finish two days ago.
It has been hot and humid here today, and my printer is in a non-AC shed not connected to the house.
I’m wondering if I should wait to kick off the next print until this evening when it should be cooler. Do I need to clean the build plate? I’ve not done that at all, other than make sure these isn’t any filament left on the plate when it finishes.
UPDATE: It’s apparent the problem isn’t the heat, but the fact that I haven’t cleaned the build plate since… well, ever. Adjusting the title to reflect that.
OK, good to know – just did an alcohol/dish soap wipe and restarted the print, will check it in a bit, and do the cleaning after every print.
If you do it before every print, you also get rid of the dust that settles inbetween prints
